cardano-ledger VS cardano-ogmios

The actual code implementing it is a little hard to find (as always with the quite convoluted and scarcely documented Haskell sources of IOG). I'd suspect it to be somewhere in https://github.com/input-output-hk/cardano-ledger/tree/master/eras.

That's just rubbish, you can stop trying to create a false narrative now. Minpoolcost was in the Shelley design spec and deliverables, it's not something **evil Charles** come up with because he felt like it.

See for yourselves all the commits in the source repo for the implementation, it is sooo active: https://github.com/input-output-hk/cardano-ledger/commits/master

The formula for the mid-ada-value can be found here. Which is essentially:

Blockchain - I find it's one of the few fields really investing in formal methods at the moment (my old boss recently opened a research center at Carnegie Mellon in formalizing maths actually). Two repos with specs are:

This is a helpful article! : https://github.com/input-output-hk/cardano-ledger/blob/master/doc/explanations/features.rst I am invested in both the ERC20 and the native token. However, there’s greater demand currently for the ERC20 tokens.

I'd suggest to use either cardano-graphql or Ogmios which both provide direct interfaces for querying stake addresses' balances.

The short answer is that, you can't. Yet, you can quite easily re-implement cardano-db-sync (or at least, the bits that are relevant for your app) on top of https://github.com/cardanosolutions/ogmios
